Willy offers a variety of fishing supplies inside, including rods, bait, tackle and crab pots. More goods become available as the player increases their fishing skill by catching fish, with the Iridium Rod being sold as soon as level 6 skill is obtained, no need to wait until the next day.

You can also sell fish or shells to Willy during daytime when he's behind his counter.

If you interact with the ladder at the back of the shop, it suggests Willy lives upstairs.

Although the door will unlock, the shop will be closed on Saturdays, unless it is raining.

If the player has not read the mail from Willy sent on the 2nd of Spring, then this shop cannot be entered.
